Here's an old file I dug up.

"A Taylor was no man" was proverbial, and they were said to be a match only for a louse. Here from the Bannatyne MS is:

[Question]
Betuix twa foxis / a crawing cok
Betuix twa freiris / a maid in hir smok
Betuix twa cattis / A Mowiss
Betuix twa telyeoris / A Lowiss
schaw me gud ser not as a stranger
quhilk of thais four is grittest in denger.

Anser
ffoxis ar fell At crawing cokkis
ffreiris are ferss At maidis in thair smokkis
Cattis ar cawtelus in taking of myuss
Telyeoris ar tyrranis in kelling of Lyiss

Cf. the ballads in the 17th century, John Taylors' "A dreadful Battle between a Taylor and a Louse" and "The War-like Taylor", and a later 18th century reworking as "A Bloody Battle between a Taylor and a Louse". I have heard a traditional version of the latter with the louse changed to a mouse. Taylors took it on the chin in many other ballads also. "In "Benjamin Bowmaneer" in DT the tailor's louse got turned into a flea.
